Of the Condition of the Offspring as to the Body
Of the Condition of the Offspring as to the Body — St. Thomas Aquinas asks: Whether in the state of innocence children would have had perfect strength of body as to the use of its members immediately after birth?; Whether, in the primitive state, women would have been born?.
We must now consider the condition of the offspring---first, as regards the body; secondly, as regards virtue; thirdly, in knowledge. Under the first head there are two points of inquiry:
Article 1: Whether in the state of innocence children would have had perfect strength of body as to the use of its members immediately after birth?
Everything generated is first imperfect. But in the state of innocence children would have been begotten by generation. Therefore from the first they would have been imperfect in bodily size and power.
By faith alone do we hold truths which are above nature, and what we believe rests on authority. Wherefore, in making any assertion, we must be guided by the nature of things, except in those things which are above nature, and are made known to us by Divine authority. Now it is clear that it is as natural as it is befitting to the principles of human nature that children should not have sufficient strength for the use of their limbs immediately after birth. Because in proportion to other animals man has naturally a larger brain. Wherefore it is natural, on account of the considerable humidity of the brain in children, that the nerves which are instruments of movement, should not be apt for moving the limbs. On the other hand, no Catholic doubts it possible for a child to have, by Divine power, the use of its limbs immediately after birth.
Now we have it on the authority of Scripture that "God made man right" (Eccles. 7:30), which rightness, as Augustine says (De Civ. Dei xiv, 11), consists in the perfect subjection of the body to the soul. As, therefore, in the primitive state it was impossible to find in the human limbs anything repugnant to man's well-ordered will, so was it impossible for those limbs to fail in executing the will's commands. Now the human will is well ordered when it tends to acts which are befitting to man. But the same acts are not befitting to man at every season of life. We must, therefore, conclude that children would not have had sufficient strength for the use of their limbs for the purpose of performing every kind of act; but only for the acts befitting the state of infancy, such as suckling, and the like.
Article 2: Whether, in the primitive state, women would have been born?
Nature's process in generation would have been in harmony with the manner in which it was established by God. But established male and female in human nature, as it is written (Gn. 1, 2). Therefore also in the state of innocence male and female would have been born.
Nothing belonging to the completeness of human nature would have been lacking in the state of innocence. And as different grades belong to the perfection of the universe, so also diversity of sex belongs to the perfection of human nature. Therefore in the state of innocence, both sexes would have been begotten.
